Question

Which of the following pairs of reactants will react together to produce water (H2O) as one of the products? a NaNO3 and H2O b Mg3(PO4)2 and Al2O3 c Fe(OH)3 and H2SO4 d Li2O and Ba(OH)2

Answer 1

The answer is C. Fe(OH)3 and H2SO4. and the equation for this reaction is given below.

2Fe(OH)3 + 3H2SO4 --> Fe2(SO4)3 + 6H2O

So for you to answer this question effectively all you need to know is how the chemical equations are written and balanced and which reactions are feasible. Remember that feasibility of a reaction normally entails whether the reaction can take place or not. So when I say feasible what I mean is whether the reaction can take place or not.
